CO2 climate sensitivity 'overestimated'

Global temperatures could be less sensitive to changing atmospheric carbon dioxide (CO2) levels than previously thought, a study suggests.

The researchers said people should still expect to see "drastic changes" in climate worldwide, but that the risk was a little less imminent.

The results are published in Science.

Previous climate models have tended to used meteorological measurements from the past 150 years to estimate the climate's sensitivity to rising CO2.

From these models, scientists find it difficult to narrow their projections down to a single figure with any certainty, and instead project a range of temperatures that they expect, given a doubling of atmospheric CO2 from pre-industrial levels.

The new analysis, which incorporates palaeoclimate data into existing models, attempts to project future temperatures with a little more certainty.

Lead author Andreas Schmittner from Oregon State University, US, explained that by looking at surface temperatures during the most recent ice age - 21,000 years ago - when humans were having no impact on global temperatures, he, and his colleagues show that this period was not as cold as previous estimates suggest.

"This implies that the effect of CO2 on climate is less than previously thought," he explained.

Well, well.

Have these experts taken the next step and admitted that global temperatures depend on the activity of the sun and the tilt of the globe?

Shhh...don't mention the immense thermonuclear reactor at the center of our solar system.

The BBC has been one of the biggest cheerleaders for the global warming agenda; pushing the scare tactics at every turn. Now that another round of emails have been released further showing the deceit and hypocrisy of the warmers, the BBC is pulling back a bit in an effort to save some face.

How can one possibly justify a massive transfer of wealth with logical thinking like that?

Its just misunderestimated.

You nailed it.

Has anyone mentioned that this year is officially an El Niño year? I was wondering why the temperatures seemed so uniform in Maryland throughout the year.

What is taking place is La Nina, which is actually the opposite of El Nino.

Now, that’s FUNNY right there!

Thanks for the correction

This article must be a hoax. Al Gore told us repeatedly that the science is settled.
